Iuvavum

Iuvavum was an ancient settlement of the Celts and, later, the Roman Empire. Located in present-day Salzburg, Austria, Iuvavum was settled around the 5th century BC, and the Gauls briefly ruled Iuvavum before its conquest by the Roman Republic in 255 BC. It became the capital of the province of Noricum after becoming a city in 15 BC, and it served as a Roman city until the fall of collapse of the Norican frontier and the fall of the Roman Empire. By the late 7th century, Iuvavum had become a ruin, and it would not be reborn until the 8th century as Salzburg.
